Light reactive lenses
Light reactive lenses
Light reactive lenses (also known as Transitional lenses) contain photochromic dyes that cause the lens to activate, or darken, when exposed to ultraviolet rays from sunlight. This means that your lenses automatically become ‘sunglasses’ when you’re out and about. Light reactive lenses offer the convenience of sunglasses without having to switch between the two.
We use ZEISS Photofusion X, the latest generation of photochromic lenses from Zeiss. Much faster than previous lighht reactive lenses, they are perfectly clear indoors and dark outdoors, providing sunglass level UV protection and a unique level of blue light blocking.
Available online and in store for an additional £100/$130, in Grey, Green, or Brown up to 1.67 index.
Please note that Photochromic lenses do not react inside cars as UV protection is already built into the windshield. If you're looking for a dark lens for driving, you will need a separate sunglass pair or a clip on.
